<br />002738 <br /> <br />As the density of adult fish is increased, the required pond space also increases. The available pond <br />space at Ouray, Horsethief, and Wahweap, including the ponds proposed for construction during FY <br />1997, totals 19.05 acres. This space appears to be allocated for brood stock development and <br />research activities. This total does not include the 5 acre riverside pond converted for use as a <br />growout pond in 1996. <br /> <br />According to Wydoski (1994a), the amount of pond space required to meet anticipated Recovery <br />Program immediate and short term needs was approximately 27 acres. Therefore, it is evident a <br />deficit of about 8 acres exists. This deficit does not include the space required for large-scale <br />restoration stocking efforts. The actual total acreage needed for backup refuge and broodstock has <br />not been estimated. Hence, substantial additional facilities would be necessary to support large-scale, <br />restoration stocking efforts. <br /> <br />8.0 Status of Recovery Program Propagation Activities <br /> <br />In Section 2.2, the stocking and genetics management actions included in the individual recovery <br />plans for the Colorado squawfish, bonytail chub, and humpback chub were outlined in detail. A side- <br />by-side comparison of the actions, as defined in the individual recovery plans, and the status of the <br />Recovery Program regarding completion of those actions defines the progress made by the Recovery <br />Program toward recovery and identifies areas needing additional attention. The following sections <br />present such a comparison for the Colorado sguawfish, bonytail chub, and the humpback chub. <br /> <br />8.1 Colorado Squawfish <br /> <br />The actions shown in bold in Section 2.2.1 are listed in the left column. The Recovery Program <br />activities associated with this action are listed in the right column. <br /> <br />1. Reintroduce Colorado squa,,1ish into <br />their historic range <br /> <br />Develop capahilities to produce <br />adequate numhers of Colorado <br />squa,,1ish for research and <br />management <br /> <br />Develop or improve propagation, <br />holding, and rearing techniques to <br />optimize production <br /> <br />Maintain a diversified gene pool <br /> <br />There are currently no plans to stock Colorado squowjish under <br />the Recovery Program. <br /> <br />Current facilities, including Horsethief SWA, Ouray EFCES <br />and Wahweap SFH are inadequate to support full broodstock <br />development and recovery efforts. <br /> <br />The Coordinated Hatchery Facility Plan (Wydoski 19940) was <br />produced that addresses the optimum loading capacities of <br />holdinglrearing facilities for different sizes of jish. No <br />production of Colorado squowjish is planned, <br /> <br />A genetic survey of Colorado squowjish was initiated in 1991 <br />to determine the genetic status of Colorado squowjish in the <br />Upper Colorado River. Nine sites were identified for genetic <br />sampling of adult squowjish. Genetic analyses have been <br />completed and a jinal report is due in November/December <br />J 996. Preliminary results indicate essentially no genetic <br />differences among jish from different sub-basins (Morizot <br />1996). The only broodstock from the jive presumptive stock is <br /> <br />38 <br />
